Struct ImmutabilityPlugin

pkg/plugin/builtin/immutability.go:34–38

ImmutabilityPlugin detects reassignment to let-declared variables and reports compile-time errors for violations. This plugin enforces Rust-like immutability semantics: - Direct reassignment: x = value (error) - Compound assignment: x += 1 (error) - Increment/decrement: x++, x-- (error) - Pointer d

// - Index assignment: x[0] = value (ok)
// - Map assignment: x["key"] = value (ok)
type ImmutabilityPlugin struct {
	ctx           *plugin.Context
	immutableVars map[string]token.Pos // varName -> declaration position
	typeInfo      *types.Info          // For pointer type resolution
}

// NewImmutabilityPlugin creates a new immutability checking plugin
